BY W M R10/hal. TTR/VEYS United States Patent O 3,088,378 PISTOL WITH SLIDABLE AND FIXED BREECH BLOCK John L. Boudreau, 655 Short Beach Road, Stratford, Conn. Filed July 5, 1960, Ser. No. 40,582 10 Claims. (Cl. 89-161) The present invention relates to an improved pistol design and more specifically to a construction and arrangement which facilitates the shooting and aiming of a pistol, particluarly where large caliber cartridges are used and where a plurality of shots are to be tired in succession.

The present invention is a species of my invention disclosed in my Patent No. 2,899,767.

It is an object of the present invention to provide a pistol capable of firing cartridges of heavy caliber with a minimum of muzzle Iift and one capable of firing a large number of shots in succession.

This is accomplished according to the present invention by providing a pistol in which the barrel thereof, which is a blow forward type cooperating with an aligned fixed breechblock, is located on the lower part of the frame so that the axis of the barrel passes through the grip in the same manner as disclosed in said Patent No. 2,899,767. Thus, even when firing a heavy caliber car tridge, the tendency for muzzle lift is substantially reduced.

A feature of the invention resides in the novel arrangement for carrying cartridges by the breechbiock in position to be inserted in the breech of the barrel and for extracting the same.

Another feature of the invention resides in a novel construction for cocking the pistol as an incident to the forward movement of the barrel, which forward movement provides for the ejection of the cartridge case and the positioning of the next cartridge to be inserted into the breechbiock upon the return of the barrel.

Another object of the invention is to provide a novel magazine for carrying heavy caliber cartridges which can be readily inserted and removed from the pistol and which provides a maximum capacity. Preferably the magazine is so arranged as to lie above and parallel with the barrel providing the proper balance for the gun.

A feature of the invention resides in the magazine having a large capacity and which can be readily iilled with cartridges and, when put in position on the pistol, releases the cartridges to be fed into the guide means on the breechblock to be fired successively.

Another object of the invention is to provide a novel sight structure for the pistol which can be easily and quickly instalied in the top of the pistol frame and can be readily adjusted to correct for windage and elevation.

Other features and advantages of the invention wiil be apparent from the specification and claims when considered in connection with the accompanying drawings in which:

As shown in the drawings, the pistol comprises a frame 10 consisting of a grip portion 11 having a trigger guard 12 integral therewith, a barrel-receiving portion 13 adapted to be secured to the grip portion and a magazine-receiving portion or member 14, as shown in FIG. 9.

When these portions are assembled by inserting the end 111 of frame 11 into socket 131 on frame 13 and are locked in place by the interlocked portions of frame portions 13 and member 14 secured to frame 11 by boits 112, as shown in FIG. 1, the barrel-receiving portion 13 is located on the lower part of the frame so that its axis is immediateiy above a trigger 16 disposed within the trigger guard and has a barrel 15 slidably mounted therein. The axis of the barrel, when extended, passes through the grip intermediate the ends of the grip. The grip has the usual side akes 17 `and is provided with a gripping surface 17a adjacent the trigger guard which forms an angle t), preferably of 38, with the axis of the bai-rei, though it may vary between 21241", and when gripped locates the barrel above the bottom three fingers and passing through the palm of the hand grasping the same and in line with the forearm.

The frame portion 11 has a breechblocl; 18 iixed therein in line with the barrel. The breechblock, as shown in FIGS. 1 and 22 to 25, is mounted in a recess 11a formed in the frame portion 11 and has a ange 20 engaging the face thereof and is heid in place by a pine 21 threaded in place.

In accordance with the illustrated form of the invention, the barrel 15 is of the blow forward type and is slidably mounted in the frame portion 13 and is normally urged to the position of FIG. 1 by a spring 22 disposed between a shoulder 23l on the frame and a shoulder 15a on the barrel and is provided with a bore 24 having a breech portion 25 at the rear end in which a cartridge 26 having the usual rimmed casing 26a is adapted to be inserted.

The other end of the barrel is threaded or otherwise secured to a piston 27 adapted to project upwardly into a cylinder 28 formed integrally with the barrel-receiving portion 13 when the barrel is in normal position. The barrel has a passage 29 formed adjacent the piston and opening into the cylinder 28 in back of the piston, as shown in FIG. 1, so that when the cartridge is fired gases will propel the bullet or nose portion 30 of the cartridge along the barrel, and as the bullet passes the passage 29, the gases will quickly pass into the cylinder and apply a forward thrust on the barrel moving it against the spring 22 and forwardly to the position shown in FIG. 3. As soon as the gases are expended, the spring returns the barrel to its normal position.

The front face of the breechlock is provided with a pair of cartridge-receiving tracks 19 for engaging the rim on the cartridge case and holding the cartridge in position to be inserted in the breech and for extracting the empty cartridge case from the breech after the cartridge has been fired.

In order to re the cartridge, the breechblock has a firing pin 31 slidably mounted therein for limited movement as controlled by cross pin 31a in slot 31b and is normally urged by a spring 32 to a retracted position as shown in FIG. 1. A striker for the firing pin is mounted on the breechblock and comprises a housing 33 slidably mounted therein and having a striker member 34 slidable in a bore in the housing and urged by spring 35 in striking direction. Referring to FIGS. l, 20` and 2l, the striker is provided with a projecting sear 36 passing through a slot 33a in the housing in position to be engaged by the end 37a of a sear link 37, pivotally mounted on depending anges 33b on the housing, and being held thereby in cocked or retracted position. The other end of the sear link has a shoulder 38 which cooperates with an actuating member 39 on the trigger so that when the trigger is depressed it causes the sear link to rotate about the pivot to release the sear and permit the striker under the urge of the spring 35 to move forward and strike the firing pin driving it against the action of the spring 32 into firing contact with the base of the cartridge to fire the same.

As shown in FIGS. 1 to 3 and 16 to 19, the barrel has a rear extension 40 formed by a pair of side rails 41 slidable in the breechblock, as shown in FIG. 25, which prevent rotation of the barrel in the frame and actuate the cocking mechanism for the pistol. The rails are connected at the rear end by a depending bridge 42. When the barrel moves forward after the cartridge has been red, the bridge 42 will move into engagement with the end 37a of the sear link and move it and the connected housing forwardly as shown in FIG. 2. As soon as the end of the Sear link passes the sear 36, it pivots and moves upwardly to a position, as shown in FIG. 3, in which the end will engage the sear on the return stroke of the barrel. As the barrel returns, the shoulder 43 on the extension 40 engages the depending flanges 33b and moves the housing and scar link into engagement with the sear and, thereafter, moves the striker and housing to the normal cocked position of FIG. l. If it is desired to manually cock the pistol, a finger-piece 44 connected to the barrel may be moved forwardly to cause the extension of the barrel to properly position the sear link and cock the striker.

If the trigger is in gripped position of FIG. 2 or FIG. 3, the shoulder 38 on the end of the Sear link will engage the actuating member in the form of a spring plunger 45 of the actuating member 39 which yields but does not pass under the shoulder. This will not permit firing of the next shot until the trigger is released, and under the urge of a trigger spring 46, moves to a position of FIG. 1 in which the plunger is disposed below the shoulder on the sear link and is ready to pivot the sear link to release the sear to fire the next shot upon the pivoting of the trigger under finger pressure.

As noted above, the breechblock is provided with guide tracks 19 for guiding and accurately locating the cartridge in position to be red. As shown in FIGS. 1 and 3, the tracks are disposed under an opening 47 in the frame and through which the cartridges pass from a magazine 48 to be guided to proper position. The guide tracks also function to extract the cartridge case after the cartridge has been fired.

ln order to eject said extracted cartridge case, the present invention provides a cut-away portion 49 at the lower left-hand track, as shown in FIG. 23, and the breechblock has an aligned groove 50 to receive a pivoted ejector finger 5`1 pivotally mounted on the extension of the barrel and normally urged by spring 52 to a position to engage behind the rim of the cartridge casing and, after the bullet has been fired and as the barrel moves forwardly, to tip the cartridge casing about the right-hand edge of the rim held in the other guide track and eject it through an ejector opening 53 in the side of the frame. The cam 51a on the frame then engages the pin 51b on the finger and retracts the finger so that on the return stroke of the barrel, it will pass the cartridge which has moved down the guide tracks to the lower cartridge inserting position, after which the spring moves the finger to a position to engage the fired casing on the next forward movement of the barrel.

The magazine `48 for the pistol is mounted to lie above the barrel and forwardly of the grip portion. While it may take many forms, in the preferred form of the invention it comprises a tubular cylindrical casing 54 having an integral closure 55 at the rear end. A pivot pin 56 is mounted in the closure for rotatably supporting a cartridge carrier 57 at that end. A fixed pivot pin 58 is mounted in a closure 59 for the forward end of the casing and projects into an axial bore 60 in the cartridge carrier. The cartridge carrier is provided with longitudinal flutes 61 which are adapted to support a plurality of cartridges 26 in end-to-end relation in each of the flutes for sequential feeding to the barrel.

In order to feed the cartridges, the casing is provided on its inner surface with a spiral feeding cam 62 adapted to be positioned between each of the cartridges in the flutes. As the carrier is rotated with respect to the casing, the cartridges cooperate with the feeding cams which move them and sequentially feed them to an opening 63 in the side of the casing which is adapted to be mounted over the cartridge-receiving opening 47 in the barrelcarrying portion of the frame adjacent the end of the breechblock. While the carrier may be rotated in many ways, it is presently preferred to provide a spring 64 disposed inthe axial bore 60 and which has one end anchored to the fixed pivot pin S8 and the other end anchored at 65 to the carrier. A stabilizing pin 66 is secured to the carrier and extends within the spring and cooperates with pivot pin 58 to control the spring as it is wound up.

While the spring may be wound up and tensioned in many ways, the most simple and convenient method is by rotating the carrier as an incident to the insertion of the cartridges into the magazine to load the same.

As the cartridges are fed into the magazine through the opening 63 into the casing, they will cause the carrier to be displaced and rotated in the casing with the feeding cam moving the inserted cartridges along the flutes. This rotation will cause the spring to be wound up and energized for rotating the carrier in a reverse direction to deliver the cartridges sequentially to the opening 63.

In order to cause the cartridges to `be moved through the opening and out of the magazine, a defiecting block 67 is `mounted in the casing at the end of the spiral cam and extends along the side of the opening 63 so that as the carrier rotates, the cartridges move sequentially into the opening and engage the deflecting block 67 which moves them downwardly and out or" the easing and into the opening in the frame to the guide tracks 19 to be guided to the lowermost position to be inserted in the breech.

As will be noted from FIGS. l to 3, two cartridges carried by the tracks are fed therealong by subsequent cartridges and by gravity into the lower-,most position. Also, it will be noted that the barrel adjacent the breech is provided with a cam surface 68 which, upon the barrel returning to normal position, will engage the cartridge above the lowermost cartridge in the track and raise it slightly, as shown in FIG. l, so as to separate it from the lowermost cartridge and prevent interference thereby with the insertion of the lowermost cartridge into the breech.

In order to insure that the last cartridge in the magazine will be delivered, the last chamber in the magazine is provided with a resilient spring unit 69 which fills the space `and which is larger than the opening so that it cannot be discharged out of the magazine but will insure the last cartridge being delivered and positioned in the guide tracks for passage to the breech.

While the magazine may be mounted in various ways, in the herein preferred form of the invention, as shown in FIGS. 4, l2 and 26 to 27, the forward and of the magazine has a recess 70 which is adapted to slip over a projection 71 carried by the frame at the top of the cylinder portion. A spring-pressed ball detent 72 is carried by the closure 59 and cooperates with a recess 71a in the projection 71 to hold the forward end of the magazine in position. The rear end of the `magasine is provided with a T-shaped rib 73 integral with the end closure S which is adapted to be inserted into the T- shaped slot 74 in the magazine-receiving portion 14 to securely anchor and locate the magazine on the frame. In order to lock `the magazine in position, the rib 73 has a notch 75 which cooperates with a latch member 76, as shown in FIGS. 3l to 34, carried by a transversely extending slide 77 mounted in the member 14. A spring 78 normally urges the slide into position in which the latch member is in engagement with lthe notch with the end portion 77a of the member projecting, as shown in FIGS. l2 and 28, to be engaged to move the slide inwardly to release the magazine. Preferably, the latch member is bevelled at 76a so as to be cammed back by the rib as the magazine is moved into place and automatically snaps into the notch when the magazine is in proper position on the frame. It will be seen that the magazine, therefore, can be readily applied to or removed from the pistol.

In order to retain the cartridges in the magazine and hold them against the urge of the spring tending to rotate the carrier, means are provided, as shown in FIGS. 29 and 30, for blocking the opening 63 in the casing to prevent passage of the cartridge therethrough. This means comprises a pivoted lever 80 mounted in a slot 81 in the deflector block 67 and projecting into the opening 63 to engage the cartridge and block the same. An actuator pin S2 projects from the end of the magazine and is engaged and actuated by the inclined end 83 of slot 84 formed in the magazine-receiving portion 14, as shown in FIGS. l1, l5 and 28, to retract the lever 80 and `release the cartridge when the magazine is slipped into final position, thus relieving the rst cartridge. A novel rear sight is provided in the top of the grip portion of the frame. As shown in FIGS. l, 4, I4 and 25, this comprises a split cylindrical sleeve 86 having a radial flange 87 projecting therefrom and provided with a sighting notch 88. The sleeve is adapted to be inserted into a transverse cylindrical recess 88a opening in the top of the frame, as shown in FIGS. l, l0 and 25, with the radial flange projecting above the top of the frame. Means for locking the sleeve in `adjusted position may take many forms. In the illustrated form of the invention it comprises a pair of opposed conical elements S9, 90 mounted within the sleeve, as shown in FIG. 2S, and connected by a threaded member 91 to draw them together and expand the split sleeve into clamping relation with the walls of the recess. With this construction the `sight can readily be adjusted for windage by sliding the sight laterally in the recess and for elevation by rotating the sight in the recess. As noted in FIGS. 9 and 14, the frame can be provided with indicia 92 for aiding in windage adjustment and with indicia 93 for the adjustment for proper elevation. The magazine at the forward end has a front sight 94 thereon to cooperate with sighting notch 83 in aiming the pistol.

From the foregoing it will be seen that the present invention provides a pistol which can be readily machined and quickly assembled and has an advantage in that it eliminates the individual spring for actuating the scar and improves the trigger-Sear relation providing a greater leverage and 1an improved trigger pull.

The construction of the barrel permits the barrel to be `manually moved forward and thus provides ready access to the gas escape port in the barrel for cleaning the same. Further, the location and compactness of the magazine provides a maximum shot capacity without interference with the design of the grip of the pistol or unduly enlarging the overall dimensions of the pistol. In addition, the feeding of the cartridges from the magazine to the breech is controlled at all times and provides for straight line insertion into the barrel, thus avoiding a tendency to bend the cartridge as in prior guns where the cartridges `move through curved paths from the magazine to the breech.

The magazine of the present invention not only provides for easy loading and positioning on the pistol but also provides for quick automatic unloading of the cartridges from the magazine when removed from the pistol and the cartridge release means is depressed.

With the pistol of the present invention greater accuracy is achieved since the tendency of the muzzle lift or jump is substantially eliminated and the barrel is maintained in line with the target at all times; thus variations in bullet delivery angle of the barrel occasioned by the muzzle jump are eliminated even when heavy caliber cartridges are used.

Variations and modiiications may be made within the scope of the claims and portions of the improvements may be used without others.
